Root canal irrigants cleaning to its best

Commentary: The success of root canal treatment in primary teeth is mainly achieved by the thorough removal of bacteria, debris, and necrotic tissue1. The complexity of the root canal system and formation of the smear layer during instrumentation of the root canal is the major obstacle for the complete elimination of bacteria during the cleaning and shaping of root canal system2. Complete elimination of bacteria requires the use of root canal irrigants3. In recent pediatric endodontic treatments, the use of traditional intracanal medicaments has been limited because of their cytotoxicity, inability to eliminate bacteria from dentinal tubules4. Recently some new irrigants such as Maleic acid, HEBP, Tetraclean, triclosan and Gantrez, Aqueous ozone, Q mix, and herbal irrigants have shown to have effectively eliminated bacteria5. The major advantage of using these irrigants are low toxicity, lack of microbial resistance, and long shelf life. Irrigants that have an antibacterial effect have superior effectiveness in bacterial elimination when compared with saline solution6. The use of irrigants such as saline, sodium hypochlorite, chlorhexidine, EDTA, & MTAD may cause damage to permanent tooth follicle and discoloration of permanent tooth bud present below7.
